I worked on this voice recognition quite a bit (free time since they scrubbed the Starship launch until tomorrow :)  and got it to work surprisingly well! Now I need to analyze the false-positive, false-negative rate. The pattern recognizer only works on frequency/phase sets, but my goal is to figure out a consonant (chaotic noise) pattern recognizer.
